Options Collar

An options collar is a position that holds a stock, buys a put below the current price and sells a call above it. The put sets a floor under the holding and the call premium pays for it, at the cost of capping the upside.

Quick Summary

  • It is three positions working as one. Long stock, a long put struck below the market, and a short call struck above it, normally with the same expiration.
  • FINRA defines the structure in its rulebook. Rule 2360 describes a collar as "a short call position accompanied by a long put position, where the short call expires with the long put, and the strike price of the short call equals or exceeds the strike price of the long put position", each hedged with 100 shares of the underlying.
  • The trade is protection paid for with upside. Whatever the stock does below the put strike stops mattering, and whatever it does above the call strike stops benefiting the holder.
  • "Zero-cost" means the premiums offset, not that the position is free. Picking a call strike close enough that its premium covers the put's leaves no cash outlay and a correspondingly tighter cap on gains.
  • The tax question is real and has no published bright line. The constructive-sale rules at Internal Revenue Code Section 1259 list four triggers, none of which names a collar, and reach anything else only "to the extent prescribed by the Secretary in regulations".

Definition

An options collar is a hedging structure built around stock the investor already owns: buy a put option with a strike below the current price, and sell a call option with a strike above it, usually expiring on the same date. The put is the floor, guaranteeing the right to sell at its strike no matter how far the stock falls. The short call is the cap, obliging the holder to sell at its strike if the stock rises past it, and the premium it brings in is what pays for the put.

FINRA's rulebook defines the structure, using the simpler name. In the equity-option hedge exemptions to its position limits, Rule 2360 describes "Collars" as "a short call position accompanied by a long put position, where the short call expires with the long put, and the strike price of the short call equals or exceeds the strike price of the long put position and where each short call and long put position is hedged with 100 shares (or other adjusted number of shares) of the underlying security". This page uses the two-word name "options collar" for a practical reason: the bare word "collar" means something else in ordinary English, including on this site, where it otherwise appears in "white collar" and "blue collar". The market and the rulebook both say simply "collar", and a reader can treat the two as the same thing.

Advanced Explanation

What the payoff diagram looks like. Below the put strike, the position's value is fixed: the holder sells at the strike, so further declines are somebody else's problem. Between the two strikes, the position tracks the stock exactly, because neither option is worth exercising. Above the call strike, the value is fixed again: the shares are called away at the strike, so further gains accrue to the option buyer. The collar converts an open-ended holding into a range, and the width of that range is the only real design decision.

Zero cost is a description of the cash flow, not of the economics. A so-called zero-cost collar chooses a call strike near enough to the current price that the premium received roughly equals the premium paid for the put, so nothing leaves the account on day one. The cost has not vanished; it has been paid in upside. Widening the floor, by buying a put closer to the current price, raises the put's premium and forces the call strike down to pay for it, which tightens the cap. Every collar is that same trade at a different point: more protection costs more upside, and there is no setting that provides both.

Where it is genuinely used. The classic case is an investor whose wealth sits disproportionately in one stock, often employer shares, and who cannot or does not want to sell: the gain is large and taxable, the position may be subject to trading restrictions, or a lockup has not expired. A collar buys time by removing the catastrophic downside while the holder works through the sale in an orderly way. That broader problem, and the other tools people bring to it, belong to the concentrated-position discussion rather than to this one.

The tax question, stated as the statute states it. Internal Revenue Code Section 1259 treats certain hedges of an appreciated position as a "constructive sale", which forces the holder to recognize the gain immediately as though the stock had been sold. Its list of triggers at 1259(c)(1) is specific: (A) entering a short sale of the same or substantially identical property; (B) entering an offsetting notional principal contract on it; (C) entering a futures or forward contract to deliver it; and (D) where the appreciated position is already one of those, acquiring the underlying property. None of those names an options collar. The only route by which a collar could be caught is the catch-all at 1259(c)(1)(E), which reaches "1 or more other transactions (or acquires 1 or more positions) that have substantially the same effect" as the enumerated four, and does so only "to the extent prescribed by the Secretary in regulations".

That conditional wording is the whole answer, and it is an uncomfortable one to give. A collar so tight that the floor and cap are nearly the same price leaves the holder with essentially none of the stock's remaining risk or reward, which is economically close to having sold it; a wide collar plainly does not. Where between those two the line sits is a question of guidance under paragraph (E) rather than of anything in the statute, and no percentage or strike-width safe harbor appears in Section 1259 itself. Anyone considering a collar on a substantially appreciated holding should get the analysis from a tax professional before the trade rather than after it, because the consequence of getting it wrong is an accelerated tax bill on a position the holder deliberately did not sell.

Two smaller points that are easy to get backwards. The FINRA rule quoted above ends with a condition: "Neither side of the short call/long put position can be in-the-money at the time the position is established." That is a requirement of the position-limit hedge exemption the rule is granting, not a rule about how an investor may construct a collar. And federal commodity law does use the word "collar" in a different sense: 7 U.S.C. 1a(47)(A)(i) lists "a put, call, cap, floor, collar, or similar option of any kind" among the contracts that can be a swap, where a collar is a single option-like contract on a rate, currency, commodity or other reference. The equity collar described here is three separate positions held together, not one contract.

How to Remember

A floor you bought and a ceiling you sold, with the ceiling paying for the floor. The room between them is the only part of the stock's future you still own.

Used in a Sentence

“Rather than sell into a large taxable gain, Theo put an options collar around his position, buying a put below the market and selling a call above it.”

How It Works

Start with the holding. An investor owns 1,000 shares of a stock trading at $62, worth $62,000, and wants to stop worrying about a collapse without selling. A standard equity option contract covers 100 shares, so the position needs 10 contracts on each leg.

Build the two legs. The investor buys 10 put contracts with a $55 strike at $2.30 each, costing 10 × 100 × $2.30 = $2,300, and sells 10 call contracts with a $72 strike at $2.30 each, receiving the same $2,300. Net cash today is zero, which is what "zero-cost collar" describes. The floor is 1,000 × $55 = $55,000 and the cap is 1,000 × $72 = $72,000.

Consider an example of each of the three zones at expiration. If the stock falls to $41, the unhedged position would be worth 1,000 × $41 = $41,000; the put lets the investor sell at $55 for $55,000, so the collar was worth $55,000 − $41,000 = $14,000. If the stock finishes at $66, both options expire worthless and the investor simply holds 1,000 shares worth $66,000, having spent nothing for the protection that was not needed. If the stock jumps to $88 on a takeover, the shares are called away at $72 for $72,000 rather than $88,000, so the cap cost $88,000 − $72,000 = $16,000.

Look at what that trade actually was. For no cash, the investor gave away every dollar above $72 in exchange for every dollar below $55. The range from $55 to $72 is the only part of the stock's future they still participate in, and whether the exchange was worthwhile depends entirely on what would have happened in the two tails. That is not knowable in advance, which is why a collar is a risk decision rather than a forecast.

One more consequence to note before the trade. A collar this tight on a position with a large built-in gain is exactly the fact pattern where Internal Revenue Code Section 1259 deserves attention, because the holder has shed most of the position's remaining risk and reward. Section 1259's enumerated triggers do not name a collar, and its catch-all reaches other transactions only as prescribed in regulations, so this is a question to put to a tax professional rather than one a payoff diagram answers.

Pros and Cons

Pros

  • It puts a hard floor under a holding without selling it, which matters when selling would trigger a large tax bill or is not permitted.
  • The short call's premium pays for the put, so downside protection can be arranged with no cash outlay.
  • Both legs are ordinary listed options, so the structure is transparent and can be built and unwound in a normal brokerage account.
  • The maximum and minimum outcomes are known in advance and can be written down before the position is opened.

Cons

  • The upside above the call strike is gone, and a takeover or a sharp rally is exactly when that hurts most.
  • Protection is temporary. A collar expires, and renewing it means paying again at whatever the new premiums are.
  • The tax treatment is genuinely unsettled at the margin: Section 1259's catch-all reaches a sufficiently tight hedge only as regulations prescribe, and no published bright line separates a safe collar from a caught one.
  • A short call against shares can be assigned early, forcing a sale at the strike at a moment of the option holder's choosing rather than the investor's.

People Also Asked

Answers to the most frequently asked questions.

What is a zero-cost collar?
A collar in which the call strike is chosen so the premium received for selling the call roughly equals the premium paid for buying the put, leaving no net cash outlay when the position is opened. It is not free. The cost has been paid in upside: to make the premiums balance, the call strike has to sit close enough to the current price to be worth that much, which is what caps the gain.
Does an options collar trigger a constructive sale?
Not automatically, and the statute is narrower than most summaries suggest. Internal Revenue Code Section 1259(c)(1) lists four triggers, a short sale, an offsetting notional principal contract, a futures or forward contract to deliver, and acquiring offsetting property, and none of them names an options collar. The catch-all at 1259(c)(1)(E) reaches other transactions with substantially the same effect, but only "to the extent prescribed by the Secretary in regulations". Because no percentage or strike-width test appears in the statute, a collar on a substantially appreciated holding is a question for a tax professional before the trade.
What is the difference between a collar and a covered call?
A covered call is one leg: the investor owns the shares and sells a call against them, collecting premium and capping the upside, with the downside left entirely open. A collar adds the second leg, using that premium to buy a put, which closes the downside below the put strike. The covered call generates income; the collar spends that income on protection.
How wide should a collar be?
There is no general answer, because the width is the trade. A put struck close to the current price protects more and costs more, which forces the call strike down and tightens the cap; a put struck far below costs little and leaves a wide range but absorbs a larger fall before it helps. The decision is about which outcomes the holder can live with, not about which setting is optimal.
Can the shares be called away before expiration?
Yes. The short call in a collar is a genuine obligation, and an American style equity option can be exercised by its holder at any time before expiration, which is most likely when the call is well in the money or around a dividend. Assignment means selling the shares at the call strike on the assigning holder's timetable, which for a position held to avoid a taxable sale is precisely the outcome the structure was meant to control.
